Цитомегаловирусная (ЦМВ) инфекция инициирует воспаление и повреждение эндотелия сосудов пуповины, что ассоциируется с нарушением фетоплацентарной гемодинамики и неблагоприятными перинатальными исходами.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Выявить биохимические и морфологические особенности эндотелия вены пуповины при ЦМВ инфекции.</p></sec><sec><title>Методы</title><p>Методы. Проведено исследование 117 новорождённых от матерей с обострением ЦМВ инфекции в третьем триместре беременности (основная группа) и 45 от матерей, не инфицированных ЦМВ (группа контроля). В крови пуповины иммуноферментным анализом определяли TNF-α, IL-1β, IL-6, эндотелин 1 и эластазу ПМЛ. Морфологически оценивали особенности пуповины.</p></sec><sec><title>Результаты</title><p>Результаты. В крови пуповины основной группы выявлялось повышение уровня TNF-α в 2,6 раза (p &lt; 0,001), IL-1β в 2,5 раза (p &lt; 0,001), IL-6 в 1,6 раза (p &lt; 0,001), эндотелина 1 в 3,2 раза (p &lt; 0,001) и эластазы ПМЛ в 1,3 раза (p &lt; 0,001). Гистологически были отмечены признаки воспаления и ремоделирования венозной стенки. Установлено уменьшение оптической плотности ядер клеток Вартонова студня в 1,14 раза (p &lt; 0,05), доли и толщины амниотического эпителия в 1,2 (p &lt; 0,001) и 1,23 раза (p &lt; 0,001), доли интактного Вартонова студня в 1,12 раза (p &lt; 0,05) при увеличении доли изменённого в 1,1 раза (p &lt; 0,05), уменьшение доли мышечной оболочки и эндотелия вены в 1,23 (p &lt; 0,001) и 1,24 раза (p &lt; 0,001), а также сужения её просвета в 1,1 раза (p &lt; 0,05). Выявлены значимые корреляции между уровнем TNF-α, IL-1β, IL-6 и долей мышечной оболочки, эндотелиального слоя и просвета вены.</p></sec><sec><title>Заключение</title><p>Заключение. Обострение ЦМВ инфекции в третьем триместре беременности характеризуется увеличением в крови вены пуповины уровня воспалительных, вазоконстриктивных и деструктивных факторов, оказывающих повреждающее действие на эндотелий сосудов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Cytomegalovirus (CMV) infection triggers inflammation and endothelial damage in umbilical cord vessels, which is associated with impaired fetoplacental hemodynamics and adverse perinatal outcomes.</p></sec><sec><title>The aim</title><p>The aim. To identify biochemical and morphological characteristics of the umbilical vein endothelium in CMV infection.</p></sec><sec><title>Methods</title><p>Methods. The study included 117 newborns from mothers with CMV reactivation during the third trimester of pregnancy (main group) and 45 newborns from CMV-negative mothers (control group). In umbilical cord blood, TNF-α, IL-1β, IL-6, endothelin-1, and polymorphonuclear leukocyte (PMN) elastase were measured by enzyme-linked immunosorbent assay (ELISA). Umbilical cord tissue was examined histologically.</p></sec><sec><title>Results</title><p>Results. In the main group, umbilical cord blood showed signifiantly elevated levels of TNF-α (2.6-fold, p &lt; 0.001), IL-1β (2.5-fold, p &lt; 0.001), IL-6 (1.6-fold, p &lt; 0.001), endothelin-1 (3.2-fold, p &lt; 0.001), and PMN elastase (1.3-fold, p &lt; 0.001). Histological analysis revealed signs of inflammation and remodeling of the venous wall. A 1.14fold decrease in nuclear optical density of Wharton’s jelly cells (p &lt; 0.05), a 1.2-fold reduction in the proportion (p &lt; 0.001) and a 1.23-fold reduction in the thickness of amniotic epithelium (p &lt; 0.001), and a 1.12-fold decrease in the proportion of intact Wharton’s jelly (p &lt; 0.05) were observed, alongside a 1.1-fold increase in altered Wharton’s jelly (p &lt; 0.05). Additionally, the proportion of the venous muscular layer and endothelium decreased by 1.23-fold (p &lt; 0.001) and 1.24-fold (p &lt; 0.001), respectively, and venous lumen narrowing by 1.1-fold (p &lt; 0.05) was noted. Signifiant correlations were found between TNF-α, IL-1β, and IL-6 levels and the proportions of the muscular layer, endothelial layer, and venous lumen.</p></sec><sec><title>Conclusion</title><p>Conclusion. CMV reactivation during the third trimester of pregnancy is characterized by elevated levels of inflammatory, vasoconstrictive, and destructive factors in umbilical vein blood, which exert damaging effects on vascular endothelium.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>цитомегаловирусная инфекция</kwd><kwd>новорожденные</kwd><kwd>морфология вены пуповины</kwd><kwd>функциональная активность эндотелия</kwd><kwd>цитокины</kwd><kwd>эндотелин-1</kwd><kwd>эластаза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cytomegalovirus infection</kwd><kwd>newborns</kwd><kwd>umbilical vein morphology</kwd><kwd>endothelial functional activity</kwd><kwd>cytokines</kwd><kwd>endothelin-1</kwd><kwd>elastase</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Финансирование исследования осуществлялось за счёт средств федерального бюджета в рамках государственного задания ФНИ (Номер государственной регистрации: 122021800166-9).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Шахгильдян В.И.
